SEECIFICATION forming part of Letters Patent No. 268,234, dated November 28, 1882.

To alt whom it may concern:

Beit known that We, ZADOK HoWE, of'Lowell, county ot' Kent, and ELLIOT OATLEY, of' Greenville, in the county of Montcalm, and State of Michigan, both citizens of the United States, have invented a new andvaluable Improvement in Uultivators; and we do hereby declare that the following is a full, clear, and exact description ot' the construction and operation ot' the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures ot' ret'- erence marked thereon.

Figure l of the drawings is a perspective view oi' our cultivator. Fig. 2 is a vertical sectional View, and Fig. 3 is a plau view of the blade.

This invention has relation to cnltivators; and it consists in the construction and novel arrangement ot' parts, as will be hereinafter fully described and claimed. Y

ln the accompanying drawings, the .letter t designates the blade, consisting of an equilateral triangular plate made plane, and having a perforation in its center, as at b, and opposite the middle oi' each side, as at c. This plate may be made ot' iron or steel. If made ot' iron, the edges and points should be chilled or faced with steel.

The standard d is made fiat from side to side, and its lower end is formed with a broad bearing, e, sufficiently long` to extend from the center to the middle ot' one ot' the edges of the blade. Above the broad bearing transverse The plate is secured to the when in position.

`standard by means of the center bolt, 7L, and rear bolt, 7c, which are inserted through the central perforation, I), and one ot the per-fora` tions c, near the rear edge oi' the plate. These -bolts also extend up through perforations l in the bearing d, which communica-te with the transverse opeuingsg, the latter affording space for the attachment of the nuts n to the upper ends of the bolts, and protecting said nuts The standard maybe adjusted in diierent angular positions with ret'- erence to the beam ot' the cultivator, and thereby the blade can be arranged in level or flat position, or at any angle desired. Either surface ot' the blade can be turned down, and either of its points mayr be turned to the front to serve as the entering or Working point ot' the blade, the adjustment being easily and quickly made bymauipulating the bolts. The blade can therefore be made to wear a long time.

Having described this invention, what We claim, and desire to secure by Letters Patent, is-

'lhe combination, with a enltivator-stamlard having a broad bearing or foot, e, having perforations Z and lateral recesses g, ot' the triangular plate or blade et, and the bolts h k and ZADOK HOVVE. ELLIOT OATLEY.
